Update Information:
# Version 20.0.0 "I Am The Sun" 2018-01-15 ## Important notes * Feature
removal: several deprecated features have been removed: * mkvmerge: the
deprecated options `--identify-verbose` (and its counterpart `-I`),
`--identify-for-gui`, `--identify-for-mmg` and `--identification-format
verbose-text` * all command line tools: support for the deprecated, old,
proprietary format used for option files * all command line tools: support
for passing command line options via the deprecated environment variables
`MKVTOOLNIX_OPTIONS`, `MKVEXTRACT_OPTIONS`, `MKVINFO_OPTIONS`,
`MKVMERGE_OPTIONS` and `MKVPROPEDIT_OPTIONS` * mkvinfo: most of its code was
re-written in order to lay the groundwork for including its functionality in
MKVToolNix GUI but with more features than the existing mkvinfo GUI. The
result is that a lot of its output has been changed slightly while keeping the
basic layout. Changes include but aren't limited to: * Several element
names are a bit clearer (e.g. `Maximum cache` instead of `MaxCache`). *
All timestamps and durations are now output as nanoseconds in formatted form
(e.g. `01:23:45.67890123`). All additional formats (e.g. floating point
numbers output in seconds or milliseconds) were removed. * Element names for
chapters and tags are now translated if a translation is available. *
Elements located in wrong positions within the Matroska document are handled
better. While mkvinfo's output is mostly kept very stable, it is not designed
to be parsed by other utilities. Even though I've tried hard to cram all
changes and cleanups into this version, additional changes may be made in the
next couple of releases depending on user feedback and bug reports. ## New
features and enhancements * mkvmerge: AVC/h.264 packetizer (framed): access
unit delimiter NALUs will now be removed. Implements #2173. ## Bug fixes *
mkvmerge: AVC/h.264 parser: when fixing the bitstream timing information
mkvmerge will now use exact representations of the desired field duration if
possible. For example, when indicating 50 fields/second `num_units_in_tick` is
set to 1 and `time_scale` to 50 instead of 5368709 and 268435456. Part of the
fix for #1673. * mkvmerge: AVC/h.264 parser: mkvmerge no longer assumes that
encountering sequence parameter set or picture parameter set NALUs signal the
start of a new frame. Fixes #2179. * mkvmerge: AVC/h.264 packetizer (framed):
when mkvmerge is told to fix the bitstream timing information, it will now
update all SPS NALUs, not just the ones in the AVCC. Part of the fix for
#1673. * mkvmerge: MPEG TS reader: TS packet payloads will only be treated as
PES packets if the payload actually starts with a PES start code. The prior
behavior led to wrong timestamps and potentially broken frame data. Fixes
#2193. * mkvmerge: MPEG TS reader: mkvmerge will now drop incomplete PES packets
as soon as an error is detected in the transport stream instead of passing the
incomplete frame to the packetizer. An error is assumed either if the
`transport_error_indicator` flag is set or if the value of the
`continuity_counter` header field doesn't match the expected value. Fixes
#2181. * mkvmerge: Opus: when re-muxing Opus from Matroska mkvmerge will now
write "block duration" elements for all block groups where a "discard
padding"
is set, too. Fixes #2188. * mkvmerge: SRT reader: mkvmerge can now handle SRT
files with timestamps without decimal places (e.g. `00:01:15` instead of
`00:01:15.000`). * mkvmerge: read buffer I/O class: the class could get out of
sync regarding the file position of the underlying file I/O class causing
wrong data to be returned on subsequent read operations. One result was that
trying to identifying MPLS files that refer to very short M2TS files caused
mkvmerge to segfault. * mkvmerge: multiplexer core: if there's a gap in audio
timestamps, a new block group/lace will be started for the first frame after
each gap. Before the fix the frame after the gap was often stored in the
previous block group causing the gap to be in the wrong place: at the end of
that block group. Fixes #1700. * mkvextract: AVC/h.264: if two consecutive IDR
frames with the same `idr_pic_id` parameter and no access unit delimiters are
found between them, mkvextract will insert an access unit delimiter in order
to signal the start of a new access unit. Fixes #1704. * MKVToolNix GUI:
update check dialog: Markdown links will now be converted to clickable links.
Fixes #2176. * build system: fixed a race condition when creating new
directories if `rake` is run with `-jN` in newer versions of Ruby/`rake`.
Fixes #2194. ## Build system changes *
[
cmark](https://github.com/commonmark/cmark), the CommonMark parsing and
rendering library in C, is now required when building the GUIs.
